Our salary is public knowledge. The salary scale is listed in payroll form where everyone in that list knows. We are paid according to salary grade so one can determine just by knowing the salary grade. When I worked with the private sector there is more confidentiality because our salary is individually paid out in a voucher.Personally speaking, I am not open to talking about the salary with my co-workers. It is a personal thing to keep and should be in confidential. I used to have colleagues who asked me this. I politely turned them down because it is not a good thing to talk about. If they have concerns like this, they can just talk to the Human Resource personnel about it.
